No, it does not mean to give your chicks a tv! Ha!
It means sitting and watching your chicks instead of tv. I think you will find there is no better entertainment than "chick tv".
Do not worry too much about what to have/do for your chicks. You will be surprised how quickly you become a pro. Just watch them, their behavior will tell you much.
One thing I will suggest, put the thermometer directly beneath the heat lamp. That is where your temp should be around 90'F (33'C). The rest of the brooder should be cooler. And lower the temp a little each week until you reach 70-75'F (23'C). After that, they won't need the heat lamp any more unless it is cold at night. Again, just watch the chicks, they will let you know if they are comfortable or not.
You are going to have so much fun.
